    md: factor out set_in_sync() · 6497709b

    Three separate places in md.c check if the number of active
    writes is zero and, if so, sets mddev->in_sync.
    
    There are a few differences, but there shouldn't be:
    - it is always appropriate to notify the change in
      sysfs_state, and there is no need to do this outside a
      spin-locked region.
    - we never need to check ->recovery_cp.  The state of resync
      is not relevant for whether there are any pending writes
      or not (which is what ->in_sync reports).
    
    So create set_in_sync() which does the correct tests and
    makes the correct changes, and call this in all three
    places.
    
    Any behaviour changes here a minor and cosmetic.
